A few months ago I successfully achieved the goal of publishing my weather station data to my local MQTT server. Now I had to decide what I was going to do with it.

Inspired

I love MQTT and learning very quickly to love Python.

For a while I've been publishing the tide data from XTIDE (http://www.flaterco.com/xtide/) on both my Merewether Weather site and the

Over the last couple of weeks I have been writing a MQTT to COSM bridge. Unfortunately (I think because of COSM) it has only been staying up and running for a few hours at a time.

My original code is here:

Thanks for Mosquitto

Hi folks,

I've just written a WeatherCat to MQTT bridge using the excellent WeatherCat Applescript interface.

MQTT allows lightweight publish and subscribe functionality and is used for process control, Arduino projects and lots of other fun things. The bridge I've written uses the open source MQTT tool Mosquitto

After upgrading to OS X Lion most of my software was working fine. But, alas, the first time I used  Oracle sqlplus (for all my Oracle scripting goodies) it died with a segment fault.

I did have a full 10.2.0.4 client installed so I tried the 64 bit instantclient and got basically the same problem.

I then

I was about to un-plug the old Linux work-horse (being slowly replaced by sexy Mac Mini Server) and realised that I hadn't converted my Currentcost Envi to work on OSX.

I initially thought it would be pretty straight-forward but after a labourious and unusual CPAN update to my perl installation I hit a road block with talking to the Prolific

The objective was to move my xtide code (http://www.flaterco.com/xtide/xtide.html) which was running on an old Fedora Linux box and get it running on my Mac Mini Server running OSX Server 10.6.5 .

I contemplated using the Mac port put together by Lee-Ann Rucker (http://homepage.mac.com/lrucker/XTide/) put it didn't include

It's not just the tides for Merewether but its the tides for Newcastle (which, lets face it, is pretty close). So you could use it for Stockton, Nobbys, Newcastle Beach, Bar Beach / Cooks Hill, Dixon Park Beach, etc.

The Merewether Tides are generated using data massaged from the brilliant program XTide 

I have updated the software that I use to update the website from my Davis Station Vantage Vue.

I am part of the way through the change from my old Linux box to a nice, small, power efficient Mac Mini Server.

The first problem was getting the Mac to talk to the Davis Station data logger. Instead of getting the Davis Weatherlink

The next step was to get the full message and then push up to a little ColdFusion XML consumer to put it all in a database structure.

Step 1:

Starting from the previous bash script I had to then grab the full message to POST up the ColdFusion website to process the data.

The bash script
